Struct CandidateHandlerRegistry 

pub struct CandidateHandlerRegistry { /* private fields */ }

Exact-name registry. Duplicate registration fails closed so a later family can never silently shadow a builtin.

Implementations

impl CandidateHandlerRegistry

pub fn empty() -> Self

An empty registry, for tests that assemble their own surface.

pub fn with_builtins() -> Self

The builtin coding-domain execution surface, matching the base catalog’s executor-backed entries.

pub fn register( &mut self, name: impl Into<String>, handler: Arc<dyn CandidateToolHandler>, ) -> Result<()>

pub fn get(&self, name: &str) -> Option<&Arc<dyn CandidateToolHandler>>

pub fn set_fallback(&mut self, handler: Arc<dyn CandidateToolHandler>)

Install the fallback handler for names with no exact registration.

pub fn has_fallback(&self) -> bool

pub fn resolve(&self, name: &str) -> Option<&Arc<dyn CandidateToolHandler>>

Exact name first, then the fallback.

pub fn names(&self) -> impl Iterator<Item = &str>
